Maths HEP Lunchtime Seminars: Pair-production of cusps on a string in AdS_3

Presented by David Vegh, QMUL

12 October 2018 13:00 in CM101

The classical motion of a Nambu-Goto string in AdS_3 spacetime is
governed by the generalized sinh-Gordon equation. It can locally be
reduced to the sinh-Gordon, cosh-Gordon, or Liouville equation,
depending on the value of the scalar curvature of the induced metric. In
this talk, I examine solutions that contain both sinh-Gordon-type and
cosh-Gordon-type regions. I show that near the boundaries of these
regions (generalized) solitons can be classically pair-produced and they
correspond to cusps on the string. For the calculations, I use an exact
discretization of the equation of motion.
